An eastern diamond back rattlesnake coils itself to strike during the Opp Rattlesnake Rodeo in Opp, Ala., March 26. The snake decline reported this week across Europe and Africa could well be happening in America, too.

Boston — The snake decline reported this week across Europe and Africa could well be happening in America as well, say biologists.

“If you get your average herpetologists together, you’d probably arrive at a consensus that a lot of scientists feel that even across their own lifetimes there are negative changes in terms of population,” says Rafe Brown, chief curator of herpetology at the University of Kansas. “It’s clear that overall the trends are not good and we’re looking at pretty serious declines.”

“The bottom line,” Dr. Brown adds in a telephone interview Thursday, "is that few of these species can survive when 99 percent of their habitat has been turned into subdivisions."

The report's lead author, Chris Reading, says he hopes that his study, the world's first global study on snake populations, will spark more herpetologists worldwide to examine their own data, including in America.

“People are concerned in the United States,” Dr. Reading says in a telephone interview Thursday from England. "It wouldn’t surprise me if it is [declining], but we don’t know.”

“The world’s reptiles are undoubtedly suffering, but the picture may be much worse than it currently looks,” Simon Stuart, Chair of IUCN’s Species Survival Commission, said in a press statement. “We need an assessment of all reptiles to understand the severity of the situation but we don’t have the $2-3 million to carry it out.”

Of note with the recent study on snakes was that the affected populations were in both protected and non-protected environments, hinting at something happening on a global scale.

Dr. Sinervo delivers a “disturbing message: Climate-forced extinctions are not only in the future but are happening now,” scientists at the University of Washington, Harvard, and Berkley write in a related article titled “Are Lizards Toast?”

Turning point?

Aside from global warming and climate change, loss of diversity and fungus-related diseases (as caused the extinction of the Golden Toad in Costa Rice) are theories for why animal life is dying off at such a rapid pace.

“It’s all of these things at once and it’s turning into the perfect storm of conservation crisis,” says Brown at the University of Kansas. “It’s like a snowball rolling downhill.”

He adds: “The hope is that we call attention to this and the role of these animals in the ecosystem.… Hopefully we look back and realize that 2010 was the year that we recognized this.”
